Q. 13.14 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the Fischer Projection for each of the following wedge-dash structures:

Step-by-Step Solution

Answer

Part a) The Fischer projection structure for the given wedged structure is shown. 

Step 1: Introduction (Part a)

• Carbohydrates are the most abundant class of organic molecules on the planet. 
• Carbohydrates account for approximately $75\%$of the dry planet's bulk.

Step 2: Explanation(Part a)

• Fischer devised a simplified method for depicting the atom configurations around the chiral carbons. 
• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Step 3: Draw the Fischer projection for given structures(Part a)

In this structure, Hydroxy and Bromide have wedged bonds, which means that in the Fischer projection there are horizontal. 

Step 4: Explanation(Part b)

• Fischer devised a simplified method for depicting the atom configurations around the chiral carbons. 
• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Step 5: Draw the Fischer projection for given structures(Part b)

In this structure, Hydroxy and hydrogen have wedged bonds, which means that in the Fischer projection there are horizontal. 

Step 6: Explanation(Part c)

• Fischer devised a simplified method for depicting the atom configurations around the chiral carbons. 
• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

Step 7:Draw the Fischer projection for given structures(Part c)

In this structure, Hydrogen and hydroxy have wedged bonds, which means that in the Fischer projection there are horizontal.
